The #24 steel water filter wrench will be the last wrench you ever need. If you have had trouble getting your housings loose during filter changes or if you have ever broken a plastic wrench, then you need our galvanized water filter wrench. It will not bend, break, or bow. This steel wrench replaces the filter housing wrench for the American Blown Filtration 2.5 in. x 10 in. clear housing.
